Heavy aromatic oil as a rubber softeners

Rubber softeners in rubber processing to improve the performance of rubber processing agents with the operation. Softener is an aromatic oil softeners, with density, high-viscosity, good compatibility, excellent processing performance, and other characteristics of the rubber industry is a good softener, as a result of containing unsaturated double bond, with the synthesis of styrene-butadiene rubber Rubber (SBR) and butadiene rubber (BR) has good compatibility, so content in unsaturated rubber keys can spread evenly, reducing rubber molecular forces between molecules, thereby increasing the plasticity of the rubber. The foreign production of synthetic rubber SBR in the largest, accounting for 52 to 55 followed by BR, in the SBR production in 75 or so for oil-filled rubber, oil-filled production of SBR consumption by the largest amount of aromatics-softeners, as a whole accounted for about softening oil Dose of 3 / 4. On the other hand, the BR to improve the processing performance and reduce costs, many countries have produced oil-filled BR, so that the oil softeners wider application. The domestic oil-filled rubber is a major oil-filled oil-filled SBR and BR, the amount of aromatic softeners softeners about 80% of the total volume.

Since the aromatics softeners to the rubber industry generate huge economic benefits in recent years to develop, research is very active. Such as: Jinzhou Petrochemical Company refinery, Jinan Qilu Petrochemical Company and refineries, and so has the use of lubricants out of furfural production of aromatic oil-mouth softeners; Anqing Petrochemical Plant will be heavy oil catalytic cracking (refining and back to the slurry) by two-solvent Refined production of rubber softener, as has been processed in Anhui, Guizhou and Rongcheng more tire plant to begin operating the mouth; quarter of allegiance to the root CGO will be used to operate out of aromatic oil, rubber tear strength and heat resistance Significantly improved alternative to higher prices of dibutyl phthalate, or high-speed oil. Aromatic softener enough, a reasonable price for the rubber industry to increase _T provides a good high or very high aromatic hydrocarbon aromatic type of rubber softeners.
